The section-wise weightage for the GATE ME exam is not officially announced by the organizing authority, which is the Indian Institute of Technology (IIT). However, based on the previous years' question papers and analysis, we can determine the approximate weightage for each section. It is important to note that these weightages may vary slightly from year to year, but they provide a general idea of the distribution of marks.

Section-wise weightage for the GATE ME exam:

1. Engineering Mathematics:
- This section usually carries around 15% of the total marks.
- The topics covered in this section include linear algebra, calculus, differential equations, numerical methods, etc.
- It is important to have a strong understanding of mathematical concepts and their applications in engineering.

2. General Aptitude:
- The General Aptitude section also carries around 15% of the total marks.
- This section tests the candidate's language and analytical skills.
- It includes topics like verbal ability, numerical ability, logical reasoning, etc.
- Practicing previous year question papers and mock tests can help improve performance in this section.

3. Applied Mechanics and Design:
- This section carries the highest weightage, around 30% of the total marks.
- Topics covered in this section include engineering mechanics, strength of materials, theory of machines, machine design, etc.
- It is important to have a strong understanding of the fundamental concepts and their applications in the design and analysis of mechanical systems.

4. Fluid Mechanics and Thermal Sciences:
- This section carries around 30% of the total marks.
- Topics covered in this section include fluid mechanics, thermodynamics, heat transfer, refrigeration and air conditioning, etc.
- Understanding the basic principles and their applications in various systems is crucial for this section.

5. Materials, Manufacturing, and Industrial Engineering:
- This section carries around 10% of the total marks.
- Topics covered in this section include engineering materials, manufacturing processes, industrial engineering, etc.
- Having a good knowledge of different materials, manufacturing techniques, and industrial management concepts is essential.

It is important to note that the above weightages are approximate and can vary slightly from year to year. Therefore, candidates should focus on all the sections and allocate their preparation time accordingly. It is advisable to analyze previous years' question papers and syllabus to get a better understanding of the important topics and their weightage.
